ENID STRUCTURE FOR RAILWAY CARS.

Application filed ecember 10, 1923; Serial No. 679,631.

T all whom'e't may concerne:

Be it known that we, `Giros-an G. LYNCi'r and LUcrUs S. PRATT, residing, respectively,

at lllilmington, .countyr of New Hanover, State of North Carolina, and at Roanoke,

i county of Roanoke, State of Virginia, and being citizens of the United States, have invented certain new and useful Improvementsfin End Structures for Railway Cars, l of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to maire and to usethe saine, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the `invention is not limited to the exact details of construction shown 'and described, as it is obvious that various modifications thereof within the scopeof the claims will occur to persons skilled in the art.

Metallic ends forrailway cars have been devised and are now in extensive use which are made of a plurality of metallic plates having parallel corrugations formed therein extending alternately inwardly and outwardly :from the neutral axis of the corrugated panel. The corrugated plate is of ample strengthto resist the shocks of the shifting lading and to resist the torsional strains setup by the weaving of the car.

lt is necessary, however, to line these metallic ends with a wooden lining so that the ca" may be used toV transportany kind of lading. The lining prevents the moisture,

due to. condensation, on the inside of the metal plate, coming in contact with the grain lading and causing`n'iildew,`or if the car is loaded with cement, this moisture would cause hardening of portions of the cementrequiring resacling. '.lhere are also limitations regarding the loading of explo-4 sives prescribed by the Bureau of EXplo-- sives of the Interstate Commerce Commission. lt is also frequently found necessary to drive nailsinto the side or end of the car when bloclringlthe lading.

Corrugated ends have been lined by positioning nailing strips within the corrugated portion and nailing the lining to such nailing strips. rllhese nailing strips, of course, are subject to shrinkage which may .cause a loose lining.

@ne of the objects of our invention is to eliminate suoli nailing strips and secure the lining boards directly to the corrugated end in such a manner that each lining board bears directly against it. Any thrust or load imposed upon the lining board is, therefore, transmitted directly to the corrugated end and acts as a beam for only the short span of the distance between the corrugations. The construction, therefore, inaterially strengthens the lining boards, thus reducing `the possibility of their breaking or splitting.l .i

Another object of the invention is to provide means to hold the boards directly in contact with the apices of the inwardly projecting corrugations. y y

Another object of the invention is to strengthen the corrugated end by using the lining to Vdistribute the load over several of the'corrugations which is accomplished by positioning the `boards vertically if the cor- -rugations are positioned horizontally or vice versa, or so that the direction of the corru gat-ion is substantially ninety degrees from the direction of the lining boards.

Another object of the invention is to provide an end lining or inner end wall for an` end of a car which can be assembled as a. unit and installed 'in the car as a unit and to provide means for` holding such unitary lining in place at intervals along the length `of the component boards and additional securing means at the top and bottom of the lining. Unitary end linings could be made up in advance of requirements and placed in stock at convenient places along the railroad. i l Y Another object of the invention is to provide means of securing a lining in place which permitssuch lining to be readily removed and replacedand which necessitates the removal of a very few fastening means, thus reducing the time the car is out of service. i i

Another object of the invention is to provide a `lining with means for resisting or re tarding warping of the component boards, which means cooperate with other parts of the carto hold the lining in place.

Another object of the invention is to provide means for movably securing a lining to a car end wall which means is entirely within the integral corrugation of a corrugated end wall so that the lining boards may bear upon the corrugations, and furthermore, the attaching means do n'ot`occup'y needed space; in other words, do not increase the train length or decrease the inside `length of lthe car. Furthermore, such means do not penetrate from the outside to the inside of the end wall of the car, which might cause a leak by `moisture following such means.

In the drawings:

Fig. l is an end elevation of a railway car with our invention applied thereon.

Fig. 2 'is across section drawn Ialong line 2 2 of Fig. l.

Fig. 3 is an enlarged fragmentary section of Fig. 2.

Fig. et is a fragmentary elevation of Fig. 3.

A plurality of `parallel lining boards forming an inner wall 1-7 are secured together by the offset ymetallic strip 30 and bolts 3l or other convenient means. The end lining maybe thus assembled asa unit 1in the wood mill in quantities and transported to the repair track for installation Ain ithe car as needed.

Rivets 88secure clips 32 within vthe corrugations of the metallic plate forming the outside wallof the car, which clips'are `provided with upturned `ianges 33 which coact with the yoffset portions of fthe strips 30. This'engagement may be loose or tight as desired. A long lianged metallic strip may be used instead tof a series of clips 3Q. The entire engaging means is -within the corrugations so that the lining may bear against the corrugations.

Means of 4fastening the 4clips 'to the corrugated end wall are positioned in the underside of the corrugations 12, which Areduce the possibility of a leak in case of a loose rivet-or bolt, and furthermore, the rivet hole vis on the neutral axis Jof the corrugated panel 'so that the reduction in strength, due to the hole, is a minimum.

To insta-'ll the assembled unitary lining it `is placed against the corrugated wallso that the lower lend of portion r34 of strip -30 is above the upper end of flange 33 and it is then Alowered -into place. The boards are vthen restricted against horizontal movement. The 2flooring 2 is then installed which retains the `lower endof the boards 117 in place.

The upper ends of the boards 1-7 are restrained against vertical kmovement by the Z-bar 35 which has a fiange 36 secured to the end wall 4and fiiange 37 overlapping the lining boards. The 'outer flange 37 is not essential, in which case the boards 1-7 might be fastened to the horizontal part of the member 35.

lVe claim:

1. In a railway car, the combination of a Icorrugated metallic -end wall, lining boards extending transversely to said corrugations, an offset strip secured to said lining boards, and a` clip vsecured to said metallic end wall, said strip co-acting with said clip to hold said lining boards close to said metallic end wall.

Q. In a railwav car, the combination of a corrugated -metallic outer end wall, a `wooden inner end wall, offset strips secured to one o'fsaid walls, and 'flanged clips secured to thevother-of said walls, said strips and-clips within said corrugation co-acting to hold said walls close to each other.
